This application claims benefit of U.S. Provisional Application No.61/155,622, filed Feb. 26, 2009. This application also claims benefit ofpriority under 35 U.S.C. §119 to French Patent Application No. 0858881,filed Dec. 19, 2009.

The present disclosure relates to a composition for dyeing or lighteninghuman keratin fibers, comprising at least one oxidizing agent, a highcontent of at least one fatty substance and at least one nonionicsurfactant comprising ethylene oxide in an amount ranging from 10 mol to80 mol.

The disclosure also relates to a dyeing or lightening process using itand to multi-compartment devices or kits.

Among the methods for dyeing human keratin fibers, such as the hair,exemplary mention may be made of oxidation dyeing or permanent dyeing.For instance, this dyeing method may use at least one oxidation dye,usually at least one oxidation base optionally combined with at leastone coupler.

In general, oxidation bases may be chosen from ortho- orpara-phenylenediamines, ortho- or para-aminophenols and heterocycliccompounds. These oxidation bases may be colorless or weakly coloredcompounds, which, when combined with oxidizing products, can give accessto colored species.

The shades obtained with these oxidation bases may be varied bycombining them with at least one coupler, the at least one coupler beingchosen, for example, from aromatic meta-diamines, meta-aminophenols,meta-diphenols and certain heterocyclic compounds, such as indolecompounds.

The variety of molecules that may be used as oxidation bases andcouplers allows a wide range of colors to be obtained.

It is also possible to add to these compositions direct dyes, which arecolored and coloring molecules that have affinity for fibers. The directdyes generally used may be chosen from nitrobenzene, anthraquinone,nitropyridine, azo, methine, azomethine, xanthene, acridine, azine andtriarylmethane direct dyes. The presence of such compounds may enablethe obtained coloration to be further enriched with tints or may enablethe chromaticity of the obtained coloration to be increased.

Oxidation dyeing processes thus may consist in using with these dyecompositions a composition comprising at least one oxidizing agent, forexample hydrogen peroxide, under alkaline pH conditions in the vastmajority of cases. The role of this oxidizing agent is to reveal thecoloration, via an oxidative condensation reaction between the oxidationdyes.

It is desired that the oxidation dye should moreover satisfy at leastone of a certain number of requirements. Thus, it should be free oftoxicological drawbacks, it should enable shades to be obtained in thedesired intensity and it should show the resistance to externalattacking factors such as light, bad weather, washing, permanent waving,or aspiration and rubbing.

The dyes should also be able to cover grey hair and, finally, theyshould be as unselective as possible, i.e. they should produce thesmallest possible color difference along the same keratin fiber, whichgenerally comprises areas that are differently sensitized (i.e. damaged)from its end to its root.

The compositions obtained should also have good mixing and applicationproperties, such as good rheological properties so as not to run downthe face, onto the scalp or beyond the areas that it is proposed to dye,when they are applied.

Many attempts have been made in the field of hair dyeing in order toimprove the dyeing properties, for example using adjuvants. However, thechoice of these adjuvants is difficult insofar as they should improvethe dyeing properties of dye compositions without harming the otherproperties of these compositions. For example, these adjuvants shouldnot harm the keratin fiber-lightening properties and the dye applicationproperties.

As regards processes for lightening keratin fibers, use may be made ofaqueous compositions comprising at least one oxidizing agent, forexample under alkaline pH conditions in the vast majority of cases. Therole of this oxidizing agent is to degrade the melanin of the hair,which, depending on the nature of the oxidizing agent present, may leadto more or less pronounced lightening of the fibers.

One of the difficulties arises from the fact that lightening processesare performed under alkaline conditions and that the alkaline agent mostcommonly used is ammonia. The use of this compound may be frequent sinceit not only may enable adjustment of the pH to allow activation of theoxidizing agent, but also may cause swelling of the fiber, with openingof the scales, which may promote penetration of the oxidizing agent andincrease the efficacy of the reaction. However, this basifying agent isvery volatile, which may make it necessary to use it in relatively largeamounts to compensate for the losses, the consequence of which is theinconvenience caused by the characteristic odor of this compound.

Accordingly, one of the aims of the present disclosure is to obtaincompositions for the dyeing, for example for the oxidation dyeing, ofkeratin fibers, which do not have at least one of the drawbacks of theprior art.

For example, one of the aims of the present disclosure is to obtaincompositions for the dyeing, such as the oxidation dyeing, of keratinfibers, with improved dyeing properties, which can achieve the desiredlightening and which may be easy to mix and to apply, and which may notrun but may remain localized at the point of application. As usedherein, the term “improved dyeing properties” is understood to mean animprovement in the power/intensity and/or uniformity of the dyeingresult.

Another aspect of the present disclosure is to propose keratinfiber-lightening compositions that do not have the drawbacks of thoseused with the existing compositions, these drawbacks being caused by thepresence of large amounts of ammonia, and which may remain at least asefficient as regards the lightening and the uniformity of thislightening.

For example, the alcohol may represent a mixture of alcohols in the sameway that the value of m represents a statistical value, which meansthat, in a commercial product, several species of polyglycerolated fattyalcohol may coexist in the form of a mixture.

In at least one embodiment, the monoglycerolated or polyglycerolatedalcohols are chosen from the C₈/C₁₀ alcohol containing 1 mol ofglycerol, the C₁₀/C₁₂ alcohol containing 1 mol of glycerol and the C₁₂alcohol containing 1.5 mol of glycerol.

For example, when present, the at least one additional surfactant ispresent in a total amount ranging from 0.1% to 50% by weight relative tothe total weight of the composition, such as from 0.5% to 30% by weightrelative to the total weight of the composition.

For example, the fumed silicas may be obtained by high-temperaturehydrolysis of a volatile silicon compound in an oxhydric flame,producing a finely divided silica. This process may make it possible,for example, to obtain hydrophilic silicas having a large number ofsilanol groups at their surface. Such hydrophilic silicas are sold, forexample, under the names AEROSIL 130®, AEROSIL 200®, AEROSIL 255®,AEROSIL 300® and AEROSIL 380® by the company Degussa, and CAB-O-SILHS-5®, CAB-O-SIL EH-5®, CAB-O-SIL LM-130®, CAB-O-SIL MS-55® andCAB-O-SIL M-5® by the company Cabot.

It is possible, for example, to chemically modify the surface of thesaid silica, via a chemical reaction generating a reduction in thenumber of silanol groups. For example, it is possible to substitutesilanol groups with hydrophobic groups: a hydrophobic silica is thenobtained.

For example, the hydrophobic groups may be:

-   -   trimethylsiloxyl groups, which are obtained, for example, by        treating fumed silica in the presence of hexamethyldisilazane.        Silicas thus treated are known as “silica silylate” according to        the CTFA (6th Edition, 1995). They are sold, for example, under        the references AEROSIL R812® by the company Degussa and        CAB-O-SIL TS-530® by the company Cabot;    -   dimethylsilyloxyl or polydimethylsiloxane groups, which are        obtained, for example, by treating fumed silica in the presence        of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus        treated are known as “silica dimethyl silylate” according to the        CTFA (6th Edition, 1995). They are sold, for example, under the        references AEROSIL R972® and AEROSIL R974® by the company        Degussa and CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by the        company Cabot.

The three compositions detailed above were mixed together at the time ofuse in the following proportions:

-   -   10 g of composition A1 (Inventive according to the disclosure)        or A2 (Comparison)    -   4 g of composition B1    -   15 g of composition C

The pH of both resulting mixtures was of 9.9±0.1.

Each resulting mixture was then applied to locks of chestnut hair (toneheight 4), at a rate of 10 g of mixture per 1 g of hair.

Each mixture was left at 27° C. for 30 minutes.

The hair was then rinsed, washed with a multivitamin shampoo and dried.

Colorimetric Results:

The coloring of the hair was evaluated visually and read on a Minoltaspectrocolorimeter (CM2600D, illuminant D65, angle 10°, SCI values) forthe L*, a*, b* colorimetric measurements.

In this L*, a*, b* system, L* represents the intensity of the color, a*indicates the green/red color axis and b* indicates the blue/yellowcolor axis. The lower the value of L, the darker or more intense thecolor. The higher the value of a*, the redder the shade; the higher thevalue of b*, the yellower the shade.

The variation in coloring between the colored locks of natural/permedwhite hair which is untreated (control) and after treatment are definedby ΔE* according to the following equation:ΔE*=√{square root over ((L*−L ₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}{square rootover ((L*−L ₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}{square root over ((L*−L₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}

In this equation, L*, a* and b* represent the values measured afterdyeing the natural/permed hair comprising 90% of white hairs and L₀*,a₀* and b₀* represent the values measured after dyeing the naturalnon-permed hair comprising 90% of white hairs.

The greater the value of ΔE, the greater the difference in color betweenthe control locks and the dyed locks.

As shown in Table 1 below, the mixture according to the disclosure,comprising more than 25% by weight of fatty substances, gave a betterlightening effect than the comparative composition comprising less than25% by weight of fatty substances.
